“…Of them, 42 species (46%) are endemics [Sen, Sureshan, 2020;Caleb, Sankaran, 2022]. Compared to few vertebrate [Vijaykumar et al, 2016] and invertebrate groups [Bharti et al, 2021;Johnson et al, 2022] whose diversity has been fairly studied, the salticid taxonomy and diversity in the WG is yet to be fully explored. Therefore, extensive surveys and studies are required to discover a real diversity of the salticids occurring in the WG.…”

AimUnderstanding the historical biogeography of the Earth's oldest terrestrial lineages provides insights into lineage diversification in relation to plate tectonics, climate change and biome shifts at maximum timescales. We investigate the biogeography of an ancient arachnid family, dragon pseudoscorpions, which are found today in mesic (mostly temperate) forests on all continents except Antarctica and Europe, have potential origins on Pangea and comprise species with extremely limited dispersal capacities. We evaluate the respective role of continental vicariance (abiotic) and biome shifts (biotic) deep in time and unravel the evolutionary history of this ancient group.LocationGlobal.TaxonPseudotyrannochthoniidae (Arachnida: Pseudoscorpiones).MethodsFive loci were sequenced for 75 Pseudotyrannochthoniidae samples collected across the globe. A matrix was compiled comprising 106 terminals and ~8800 bp, and phylogenetic analyses were performed to uncover relationships. Divergence time and ancestral range estimation analyses were used to reconstruct historical biogeography.ResultsPseudotyrannochthoniidae was monophyletic with high support but relationships among genera did not reflect current taxonomy and instead showed geographical structuring. Pseudotyrannochthoniidae originated in East Asia during the Middle Triassic and began diversifying in the Early Cretaceous.Main ConclusionsDiversity and distributional patterns of dragon pseudoscorpions can be explained by the interplay of continental vicariance through Pangaean breakup, and biome shifts via the spread of temperate habitats in the Cretaceous and their ongoing distributional fluctuations. Pseudotyrannochthoniidae diversification began in the Early Cretaceous as they dispersed with temperate forests across the Northern Hemisphere. Cretaceous vicariance, followed by widespread Holarctic extinction in the Late Tertiary–Quaternary, created their disjunct distribution at northern latitudes. Northern and Southern Hemisphere lineages diverged as Gondwana and Laurasia rifted, and Gondwanan breakup resulted in Afrotropical/Indomalayan and Austral clades. Austral lineages spread with temperate forests, however, cooling caused their disappearance from Antarctica and led to disjunct distributions at low latitudes.

“…Fragments of one mitochondrial and two nuclear genes were sequenced using standard Sanger methodology for this study and these sequences have proven to be useful in reconstructing pseudoscorpion phylogeny in a range of different taxa (Murienne et al 2008;Harvey et al 2015Harvey et al , 2016aHarvey et al , 2016bHarvey et al , 2020Harms et al 2019;Johnson et al 2022;Hlebec et al 2023). The present study included fragments of the cytochrome c oxidase subunit I (COI), 18S ribosomal RNA (18S) and 28S ribosomal RNA (28S).…”

The pseudoscorpion family Garypinidae is globally distributed with 79 species in 21 genera and several species represented by Mesozoic and Eocene fossils. This was recently included with the family Larcidae in a unique superfamily, Garypinoidea but there are no phylogenetic hypotheses for the group. Sequence data were obtained for 14 species in 8 genera and numerous outgroup taxa that formed the basis for a preliminary molecular phylogeny. A new subfamily classification is proposed with Protogarypininae, subfamily nov. comprising five genera mostly found in the southern hemisphere, Amblyolpiinae subfamily nov. comprising two genera and Garypininae for the remaining genera. Several new taxa are described including the first Australian species of Aldabrinus, A. rixi sp. nov., a new genus from South-East Asia, Nobilipinus, comprising Nobilipinus nobilis (With, 1906), N. vachoni (Redikorzev, 1938) (that is removed from the synonymy of G. nobilis) and five new species, N. affinis, N. galeatus, N. karenae, N. kohi and N. tricosus, and Solinus pingrup sp. nov. from south-western Australia. Paraldabrinus Beier, 1966 is newly synonymised with Aldabrinus, and Indogarypinus Murthy and Ananthakrishan, 1977 is newly synonymised with Solinus. The holotype of Garypinus mirabilis With, 1907 from Hawaii is redescribed but found to be a tritonymph, rendering the generic identity uncertain.
